This is caused by the unchecked growth of micro-organisms which form a slimy biomass. The effect of the biomass is to restrict water flow, reduce system capacity, and inhibit heat transfer much the same as with deposition. The types of organisms most often encountered in industrial water systems are: Bacteria Algae Fungi Protozoa Some organisms…
